Igcse Model Questions Vol1 2020 Chemistry Question 36
Practice objective / multiple choice question 36 from the 2020 Igcse Model Questions Vol1 Chemistry examination.
A 46.0 g mixture of ethanol (CH\(_3\)CH\(_2\)OH) and 1‑propanol (CH\(_3\)CH\(_2\)CH\(_2\)OH) is distilled and the boiling point of the mixture is found to be 85.0 °C. The boiling points of pure ethanol and pure 1‑propanol are 78.4 °C and 97.0 °C respectively. Assuming the boiling point varies linearly with the mole fraction of ethanol, determine the mass of ethyl acetate (CH\(_3\)COOCH\(_2\)CH\(_3\)) that can be formed when the mixture reacts completely with excess acetic acid according to the esterification reaction. (Molar masses: ethanol 46.07 g mol⁻¹, 1‑propanol 60.10 g mol⁻¹, ethyl acetate 88.11 g mol⁻¹.)
